Metric Conversions for Nursing

Correct Answer: A

Rationale: The prefix 'Tera' corresponds to the value of 10^12. This can be understood by knowing that the International System of Units (SI) prefixes are based on powers of 10. 'Tera' comes after 'Giga' (10^9) and before 'Peta' (10^15). Therefore, the correct choice is A. Summary of other choices: B: Incorrect because 'Giga' represents 10^9. C: Incorrect as 'Peta' represents 10^15, a higher value. D: Incorrect because 'Mega' represents 10^6, a lower value than 'Tera'.

Correct Answer: A

Rationale: To convert 0.875 to a fraction, we first note that the decimal places indicate the denominator. Since there are three decimal places, the denominator is 10^3 = 1000. Then, 0.875 = 875/1000, which simplifies to 7/8 by dividing both the numerator and denominator by 125. Therefore, the correct answer is A (7/8). The other choices are incorrect because B (8/7) is the reciprocal of the correct answer, C (3/4) and D (9/10) do not equal 0.875.

Correct Answer: A

Rationale: To convert 0.07 to a fraction, we note that 0.07 = 7/100. The rationale is to move the decimal two places to the right to get the numerator and place it over 100 (10^2) to get the denominator. Option A (7/100) is correct. Option B (1/10) is incorrect because it represents 0.1, not 0.07. Option C (1/20) is incorrect as it represents 0.05. Option D (1/50) is incorrect as it represents 0.02.

Correct Answer: A

Rationale: To convert 0.875 to a fraction, we note that it is 875/1000. Simplifying this gives 7/8, making A the correct answer. Choice B, 9/10, and C, 5/6, are incorrect as they do not equal 0.875 when converted to decimals. Choice D, 3/4, is also incorrect as it is not equivalent to 0.875.
